The grocery store where Ms. Maple works pays her $6.50 per hour. Any time she works more than 40 hours per week, she is paid tim

Charra [1.4K]

Answer:

$289.25

Step-by-step explanation:

First we should find out how much Ms. Maple would make in a week without overtime.

6.5 x 40 = 260

Now, let's figure out how much she makes per hour in overtime.

6.5 x 1.5 = 9.75

Now add up the hours of overtime.

9.75 x 3 = 29.25

Now we add the weekly wage to the overtime

260 + 29.25 = 289.25

For 40 hours of regular time at $6.50/hr and 3 hours of overtime at $9.75/hr, Ms. Maple will make $289.25 for the week.

A triangle has angle measures of 47 degrees and 92 degrees. What is the measure of the third angle?

ludmilkaskok [199]

Answer:

The missing angle is 41 degrees

Step-by-step explanation:

First of all, a triangle is measured at 180 degrees in total

To find the missing measurement for the third angle, add the 47 and 92 degrees together which would equal 139 degrees.

47+92=139 degrees

Next just subtract 139 from 180 to get your answer.

180-139=41 degrees

The answer is 41 degrees

Hope this helps

Please help guys!!!!!!!!!!!!!!

Answer:

a) x = -10

b) x = 7

Step-by-step explanation:

2(x + 3) = x - 4

2x + 6 = x - 4

2x - x = -4 - 6

x = -10

4(5x - 2) = 2(9x + 3)

20x - 8 = 18x + 6

20x - 18x = 6 + 8

2x = 14

x = 7

Someone help me with these two. I'll give you brainliest and 25 points!! MATHEMATICIANS OUT THERE HELP

Hello LovingAngel!

To find the slope, you can use the formulas $\frac{rise}{run}$ as well as $\frac{y^2-y^1}{x^2 - x^1}$ . I am using the latter to calculate and ensuring my answer with the former.

[Note: (x,y) is the format for ordered pairs]

First pair: value 1:(1,5) and value 2:(2,8)
$\frac{y^2-y^1}{x^2 - x^1}$ -> $\frac{8 - 5}{2 - 1}$ -> $\frac{3}{1}$ or 3.

The slope for (1,5) and (2,8) is 3(/1).

Second pair: value 1: (3,1) value 2 (3,-1)

$\frac{y^2-y^1}{x^2 - x^1}$ -> $\frac{-1 - 1}{3 - 3}$ -> $\frac{-2}{0}$
Slope for the second pair is -2/0

Checking work with $\frac{rise}{run}$
1. Slope: 3/1, meaning rise (y) +3 and run (x) +1. (1,5) -> (1+1,5 + 3) -> (2,8) ✔
2. Slope: -2/0, meaning rise (y) -2/drop (y) 2 and run 0. (3,1) -> (3 + 0, 1 + -2) -> (3,-1) ✔
